Abstract
An optical apparatus for imaging a sample has a scanning apparatus having a laser energizable to direct an input beam of a first wavelength to a reflective scanner that is rotatable about an axis and a toroidal mirror surface that is symmetric about said axis and is disposed to direct scanned laser light of the first wavelength toward the sample in an arcuate scan pattern. A compensator in the path of the input beam is formed to correct one or more aberrations of the toroidal mirror surface. Telecentric collector optics define a collection path that conveys, to a detector, scanned light of a second wavelength that is excited from the scanned sample.
